This debuted earlier with subs this week. It's only 6 minutes but I love most of Makoto Shinaki's work so I decided to watch it. It was definitely sweet though with the family-like atmosphere. And...the animation was glorious although I wasn't too surprised by that. For a story though, it was short and sweet just the way it ought to be.

Makoto Shinkai does slice of life very well.
This particular story wouldn't be well served by being longer, imo. It really is the anime equivalent of a short story. Short, sweet, and to the point.
